. come by various means; but the processes charge can alone be depende com hitherto in use are lengthy and expensive and sometimes exceed the desired efi'ect, the said rocesses being generally based on the coatmg of thechlorate with mineral or vegetable, fatssuch as oils, tars, paratfins, or resinseither alone or mixed with other combustible or exciting materials by simple juxtaposition or by dissolution. Used alone the coating materials attenuate the sensitiveness of the chlorate to such an extent that the explosive mixture explodes only with difiiculty under the shock of the fulminate and the decomposition is incomplete oreven impossible if the charge, though small, is arranged so as to form a row of cartridges, as is usual in mining'g erations. The inflammability, however grea "'it may be, is never such that the simple .i 'tion of the on, and the ustion is too slow. The result is the same and the manufacture often more com plicated lfexciting materials be used with the coating material, the coating material the reaction of t e excitant from ta -ingplac e.. On the other hand, s eve'ralof these exciting -acting as a damping obstacle and reventing materials such as sulfur in the free state or in combination, picric acid, and raw tarare liable, owing to their natural or acquired acidity, toeventually cause sudden and spontaneous decompositions.

The improvement constituting my invention obviates these disadvantages and consists as follows: First, melt in avessel heat-' ed by steam or hot water a solid nitrated derivative of t0luenosuch as paranitroto- 'luol, dinitrotoluol, trinitrotoluol, or a mixture of these bodies, which may be liquid; second, 'incor orate in the liquid thus obtained the chl orate or perchlorate of potassium or other chlorate or finely-ground state; third, a low the mass to cool until crystallization takes place ;fourth,

to obtainit in ulverulent form sift this mass to the require size of grain.

put up in cartridges in the usual or any suitable way.

The following formula gives an example of such explosives, the (proportions of which may of course be varie according to requirements: dinitrotoluene, twenty-five per cent; chlorate, seventy-five per cent.

What I claim is.

1. A process which consists in melting a solid nitrated derivativeof toluene and incorporating in the liquid mass a chlorate'salt.

2. An article of manufacture consisting of a mixture of a nitrated derivative of toluene and a chlorate salt. A

In testimony whereof I have hereunto set my hand in presence oftwo subscribing witnesses.
